Percival Roofing & Maintenance | Alta Vista Roofing Services

"Our flat roof on the garage had been patched five times by other companies. Percival Roofing & Maintenance stripped it and put on a proper TPO membrane. No leaks in two years. Should have called them first."

"Emergency tarping after a windstorm ripped our ridge cap off. Percival Roofing & Maintenance had a crew out within three hours and tarped the exposed section before rain moved in. Saved us from interior water damage."

"I called about a small leak and expected a hard sell on a full replacement. The inspector showed me it was just a cracked pipe boot — $300 repair instead of a $12,000 roof. Honest company."

GAF Master Elite Certified

Only 2% of roofing contractors in the country hold GAF Master Elite certification. That gives Alta Vista homeowners access to the Golden Pledge warranty: 25 years on workmanship, 50 years on materials. It's the strongest warranty in the industry.

Manufacturer-Certified Installation

We hold certifications from GAF, Owens Corning, and CertainTeed. That means the manufacturers have trained and vetted our crews and will back our installations with their strongest warranties. Your Alta Vista roof gets factory-level quality control.

Storm Damage Specialists

Hail, wind, and monsoon damage are common in IA. Our team includes HAAG Certified inspectors who document damage the way adjusters expect it. We handle the entire insurance claim process so you don't have to.

No Subcontractors

Every Alta Vista roof is installed by our own trained crews, not subcontractors pulled from a labor pool. That means consistent quality, accountability, and a crew that knows our standards from the first nail to the last drip edge.
